Application filed .anuery 27, 1914. Serial No. 814,813:

To'aZZ whom t may concern Beit known that I, GEoIGnI. HIPPLE a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new 'and useful Improvements in Tire-Pumps; and I do hereby declare the following to be af] full,- r

clear, and exact ydescription of the invention, such as will enable others skilled inthe art to which 4it appertains to make and use, the saine. f l

My invention relates to` air-compressing pumps and more particularly tor the classof pumps used for inflating the tires of automobiles.

One object of my invention is to `provide :i tire pump which may readily be attached to the, running board or other rigid portion of fra-nie of a vehicle sofas to be firmly held-ijn position when in use, and to equip such a. pump with a clamp adapted to he housed by the iframe of the vehicle when not in use. i i

Another object is to equip a manually o'p` erable pump with an operating lever adapted to provide great leverage when in use and be folded into` a comparatively `small space when not in use. I

A further object is to provide the members comprising suoli a folding lever with simple, manually operable means :tor rigidly securing the same in their extendedrelation, and f with engaging formations adapted to relieve` the said connection oi' excessive strain when the pump s in use.

n btill another object 1s to equip a pumping mechanism with a lever provided with =a pluralitflvv ot' hund-hold ilorinations so disposed that the leverage iimy readily be vnricd-.sor that the puiiip may be quickly operated*at Y tion. Fig. 2 is a plan view of the pump withr the members of the operating lever folded for storage. F10. 3 is zin-elevation or the eX-` lt b i tension portion of the operating lever and of a portion of` the main' member oic the said` lever. Fig. 4 is a sectionalvicw through a portion o f the lever of Fig. 3, along the lines 4%. Fig. y5 is a fragmentary `end vieW of .i

the pumpshowing the method of clamping the same to the running board ofthe Vehicle.

HSG. I y Iny the drawings, the tire pump of my invention consists essentially of a baseer supvation of the pump'as it appears when in porting member 1 having a frame 2 edapted `to rest upon a running board Stor other rigid y object, and to be clamped to such an object by a clamp All. 'The clampy 4: preferably con` sistsof an angle-shaped member. 5`pivoted at one end to. a side portion of the frame 2 and having a ythuinh-screw 6 threadedly engaging the other end 11 of the seid member and equipped with an enlarged foot 7. y Whenthe olzinipis disposed substantially at i right angles to the frame 2 of tliegjbase, the I said foot 7 will eoact `with the base `upon rof tation 'of the screw 6 to clump the hoard 8 between the base 2 and the foot'io'Y the'sorew1 thereby securing the said haseand the pump mechanism 4carried thereby to the boardy 8.

' s n l f n l Fig. 6 isv a central. longitudinalk section: through the pump. Fig. 7 is areduced ele-y 'lokr One oi the longitudinal members 9 of' the i hase ispreferably equipped with. a recess 10 adapted to be entered by the end portion 11;

`of the clamp when the latter is moved to a position substantial parallel Witlgfthe seid frame (as inV Fig. l), so that tliesaid clamp i may be substantially housed by theibase to make the device moi'ecompact for storage.

The supporting member l isequip'jped at.

one end with a pair` of trunnions-l2 having pivots for a shaft 13 extending through a -pair of lugs lftupon the rear end 15 of a cylinder 1li, which cylindenis equipped with suitable inlet rand outlet valves 17. Within the cylinder 1G I position a piston 1S- equipped with `a suitable: packing, 19 and with a rod 2 0 extendingv slidingly through the; forward hefid`42l of the cylindery and se-y cured otite free end to'a cross-bar 22. The

cross-bar 22 is pivotally securedto :i pair of, f

parallel arms 23 and 24, which arms are pv` oted to a common shaft 25 carriedeby the base 1. The 'arm 24 is lelongated past the end by` a pivot .2G K which extension arm may hedisposed sub in Fig. 7), Wherebythe-arms 2li and 27 n com- ,los cross-'bar 22*y anduis connected near 'its rear to'an extension arm 27,A

` stantially as an elongation of the Win24 (as v y bine to form .an operating. le ver which will r'be relatively" long in proportion tothe dis? tance between the cross-bar 22 and the shaft E25, which shaft serves as a. fulcrum for the said operating lever. The main portion 24 of the operating lever is equipped with a shoulder formation 28 adapted to engage an adjacent portion of the extension arm 27 so as to transmit the strain from the extension 2T to the main arm 1G when the former is moved in the direction shown by the arrow 29 in Fig. 7, this being 'the direction in which the operating lever is moved to compress the air in the tire. To prevent a relative motion of the lever portions 27 and 21 upon a motion of the extension portion 2T in the opposite direction, I secure the said lever portions to eachother by a thumb-screiv 30 slidingly swiveled upon a` recessed portion 31 carried by one of the lever portions, the other of said portions being equipped with a thread 32 adapted to be engaged by the said screw. Extending transversely through the shank of the said screw is a suitable fastening, such as a cotter 33, which will prevent the screw from being entirely withdrawn from the recessed portion 31 housing a portion thereof, but which Will permit the screw tobe retracted suiiiciently to enable the lever portions to be moved about their connecting pivot 26 when the lever portions are to be folded along-side of each other as in Fig. 1. t

The extension portion 2T of the operating lever is equipped at its outer end with a. hand-hold formation 34 adapted to aiord a suitable-grip so as to prevent a slipping of the hand of the operator, and is also preferablyequipped with another hand-hold formation 35 disposed nearer to the pivot 26, each of these formations being bordered by tangibly appreciable ridges which will prevent a slipping of the lingers grasping the formation bordered thereby. It will be4 obvions from liigj? that the leverage afforded by theoperating lever will be varied according to the hand-hold gripped by the operator. It will also beobvious that the shorter leverage will afford less power and will require the arm of the operator to be moved through a shorter distance. Consequently, the operator of my pump can readily Werl; the same speedily by gripping the hand-hold 35 When first starting to use the pump. Then after a sufficient pressure has been created the tire to oil'er a considerable resistance` L the action of the pump, the operator cant` readily change his grip to the hand-hold 34, thereby securing the increased leverage. It Will also be evident that by drawing back the thumb-screw 30, as in Fig. 4, the lever portions can readily be folded along-side of each other, as in Fig. 2, thereby reducing the pump of my inventin to a very compact `form for storage.

While I have shown and described the shoulder formation 28 as formed upon the main portion 36 of the operating lever, and

have shown the recessed portion. 3l as formed upon the extension portion 27 of the said lever, I do not wish to be limited to this or other particular details of the construction herein disclosed, since the latter might be varied considerably Without departing from the spirit of my invention as shown in the appended claims.

I claim as my invention:

l. In al pump, the combination with a pumping mechanism, of an operating lever connected thereto, an extension arm pivotally connected at one end to the said lever intermediate of the ends of the latter, and a screw swiveled upon the arm and threadedly engaging the lever to lock the lever against pivotal motion with respect to the arm.
